The Funk Bottoms 50, (which is actually 60 miles, but who's counting!), is an event taking place soon in Ohio. Looks to be a fun and challenging event. Plus- it's free, (with the exception of lottery ticket purchases to verify you've been on course), and based on rules from the Pirate Cycling League.
Good stuff here, so check out the link for the October 6th event here.
This is a clearing house of information for gravel road/un-paved back road oriented events. If you would like to see a link to your event here, just e-mail me. (email@example.com) Likewise, if there are race reports, photos, or news you want to share, hit me up with it. This is your gravel road site- make it happen!
Note: Any info sent to me on a ride or event you want to have appear here must have a clear and easy to find website/blog/or on-line flyer. If I can't find the info easily, I won't post your story/info.
